c# - Adding Methods To Windows Form? -

i have 2 windows forms, parent , child. parent main form. child dialog user can edit details.

when button clicked on parent form, loads child form. so:

private void add_account_click(object sender, eventargs e) {      this.account_add_edit = new form2();      account_add_edit.test();      account_add_edit.showdialog(); } 

as can see i've created new form, tried call function new form, , showed form. problem method form not being called. getting error on ide says windows.forms.form not contain method test.

i've created method in child form:

public static string test(string val) {     this.username = val; } 

any ideas i'm doing wrong?

your method defined static , not posiible call on instace. should eaither not make static, or call static:

form2.test();
